ASTM A514 equivalent to us steel materials T-1 or T1 ?

A514 steel materials belongs to ASTM A514/A514M specification high yield strength,Quenched and tempered alloy steel plates which stuitable for welding,ASTM is the Acronym of American Society of Testing Materials.However,T-1 or T1 belongs to ArcelorMittal USA plate steels is a group of quenched and tempered constructional alloy steels with an attractive combination of advantages and characteristics.All steel grades in A514 and T-1 owned minimum yield strength above 690Mpa / 100 Ksi.As per chemical composition,A514 Grade F equivalent to T-1.T-1 type A is similar equivalent to A514 Grade B,T-1 type B is equivalent to A514 Grade H in chemical composition.

Heat treatment with Quenched and tempered,low temperature impacting test normally at -50 Deg.C and Ultrasonic examination comply to astm a435/a435m,a578/a578m shall be done for steel materials astm a514 grades and Arcelormittal T-1 steel materials typy.
